11 Claims. 1

The invention herein disclosed is known under the trade name Hassock-bed and comprises a new article of furniture which can be used either as a bed or as a hassock, and beconverted at will from the one type of furniture into the other.

Special objects of the invention have been to enable the quick and easy conversion from the one form of furniture into the other and to have in each instance a fully useful and practical structure, that is, the bed in the one instance and the hassock in the other instance.

More specifically it has been a purpose of the invention to enable the conversion to be accomplished practically in a single continuous operation, the hassock to be opened out into a bed in a continuous unfolding operation and conversely, the bed to be changed back into a hassock by a simple and practically continuous folding andclosing operation.

Special objects of the invention also are to so counter-balance the parts that only slight effort will be required to effect the unfolding and folding operations.

It is a purpose of the invention also to insure that the parts will be firmly and securely locked in the closed. or folded condition, but in such a way that they may be quickly unlocked when the conversion from hassock to bed-forming structure is to be made.

Other important objects of the invention are to accomplish all the foregoing with a relatively simple and low cost form of construction.

Other desirable objects and the novel features through which the purposes of the invention are attained are set forth or will appear in the course of the following specification.

The drawings accompanying and forming part of the specification illustrate a present practical embodiment of the invention but structure may be modified and changed as regards the immediate illustration, all within the true intent and scope of the invention as hereinafter defined and claimed.

Fig. 8 is an enlarged broken part sectional detail of the lock mechanism as on substantially the plane of line 88 of Fig. 7;

Fig. 9 is a perspective view showing how the device may be shortened for use as a childs bed, by folding under the end frame section and placing a bed or crib-forming frame about the shortened frame structure;

Fig. 10 is a side elevation of the parts in this latter condition, providing the childs bed;

Fig. 11 is a plan view of the folding frame which can be attached to form the sides of this bed;

Fig. 12 is an enlarged broken sectional detail showing how the folding frame may be secured to the headboard.

Fig. 1 shows the invention in use as a hassock, with a slip cover I 5 over the cushion it whichforms the top of the folded hassock-forming structure shown in Fig. 2.

This single cushion IS, in addition to providing the top of the hassock, cooperates with a foldable, double cushion ll, as shown in Figs. 3 and 4, to provide the complete, full length bed mattress.

These coextensive mattress-forming cushions are mounted so that the double length cushion will automatically unfold and line up with the single cushion as the latter is lifted and will automatically fold up beneath the single cushion as the latter is returned to position over the hassock base.

The base of the hassock, last referred to, is indicated in several views as a substantially rectangular frame l8 to rest on the floor, having a pair of upright posts l9 at the corners which become the head of the bed, and a pair of shorter upright posts 28 at those corners which are located intermediate the length of the bed.

The latter posts provide the pivotal supports for the hingedly connected frames 2|, 22, which carry the folding sections of the double mattress cushion.

The outer or end frame 2| is shown pivotally connected with the inner or intermediate frame 22 by hinge links 23 having the pivot connections 24, 25, at opposite ends.

These double jointed hinge connections enable the cushion to fold smoothly, as shown in Fig. 2, without cramping'or squeezing.

' The end-frame 2| is shown supported at the outer end by'toggle links 26, 21, pivotally connect'ed together at the center, at 28, and pivoted at the ends, at 29, 30, to end frame 2! and to the base, respectively. The center pivots are shown connected by links 3| to pivot pins 32 on the ends of levers 33 which are pivoted intermediate their ends at 34 on posts 20, and have their opposite ends pivoted at 35, underneath frame 22 at the far side of the hinge pivot 25.

As a result, the lifting and unfolding operation of the intermediate frame 22, as shown .in Figs. 3 and 4, will impart a straightening action to the toggle links 26, 21, to lift the outer end of end frame 2|.

At the same time, the inner end of this frame is guided up into horizontal position by links 36 engaged with pivots 34 on the posts and ,pivotally connected with the inner end of the frame at 31.

In the fully extended, horizontal relation shown in Fig. 4 the end and intermediate frames 2| and 22 are locked by toggle links 38, 39, pivotally connected together at the center at and pivoted at their outer ends at 4|, 42, with downwardly angled extensions 43 of the frame 2|, and with frame 22. This toggle linkage and interlocking relation prevents breakdown of the hingedly connected frames under application of undue or excessive pressure.

The downwardly inclined extensions-43 for the connection of toggle links 38 and 39 cause these links to break at the center connection 40 as the bed starts folding from the Fig. 3 to the fully folded, Fig. 2, position.

The frame 44 for the single top cushion I6 is shown as pivotally connected at 45 with the intermediate frame 22 so as to fold over and carry cushion l6 over the top of intermediate frame .2

22 as the three frames are hinged over each-other from the Fig. 3 to the Fig. 2 position.

The outer ends of intermediate frame 22 and end frame 44 are supported by leg members 45 and 41, the latter rigidly secured to frame 44 at 48 and the former pivotally secured to frame 22 at 49.

Links 50, pivotally connected with the outer frame 44 at 5|, and pivotally connected at 52 with legs 46, serve to lower the latter into position for supporting the intermediate frame in horizontal relation as the structure is drawn .out to the Fig. 4 position. These links .50 serve to fold the pivoted legs 46 in the reverse, folding operation, as indicated in Figs. 3 and 2.

In the completely folded condition, upwardly projected, angular extensions 53 of legs 46 engage in projecting brackets 54 on posts 19 to aid in looking and securing the parts in fully folded relation,

To look the inner or intermediate set of legs 46 against collapsing tendency, the outer frame member 44 is shown provided with dependent lugs 55 to bear upon the leg extending struts .50 in the fully extended position of the parts shown in Fig. 4.

The three hingedly connected frames'2 22 and 44 are shown in Fig. 5 as carrying suitable mattress supporting springs 56 foldable on the hinging lines so as not to interfere with the free folding and unfolding operations described.

To further facilitate the unfolding and folding operations the parts are balanced and counterbalanced in the illustration by elongated helical springs 51 connected between an intermediate lug 58 on the end of end frame 2| and outer corner posts I9, Figs. 5 and 6, and a spring 59 connected between this lug and the mid-portion of the base at '60, Fig. .3. Other extension springs, 6|, are shown connected between the end pivots 4 32 of levers 33 and anchorage points 52 in the outer corners of the base.

These springs have the effect of partially supporting and counter-balancing the pivotally mounted frame sections, enabling the latter to be smoothly and easil drawn up out of and returned to relatively folded relation in the base.

The parts are preferably balanced so as to be biased in the folding direction, and in addition it has been found desirable to lock and secure the structure in the closed, folded condition.

The locking mechanism is shown as consisting of a rod 53, Figs. 2, 7 and 8, journaled in bearings 64 beneath the outer end of the outer or upper frame section 44, carrying at the center a hook 65 engageable with a catch 66 attached to the hinge links 23 connecting the inner and intermediate frame sections 2|, 22. A spring 81 connected with an upward extension 68 of the hook tends to rock the hook into engagement with the catch or keeper, the extent of the spring movement being limited by the stop 69, Fig. 8. Movement in the opposite direction is limited by a front stop 10 engageable by hook extension 63.

An inclined cam'll, Fig.8, guides and opens the hook, in the closing movement of the frames, to effect engagement with the catch 66, and cylindrical handles 12 on the end portions of the rod 53 serve for rocking the rod to release the hook from the catch.

In use the handles 12 provide grips for one or both hands, for unlocking the parts and pulling the frames out into th extended relation.

A headboard I3 is shown pivoted to the inner end of the inner frame 2|, at .14.

This headboard is automatically raised and lowered in the opening "and closing operations and is further utilized :to assist in folding andholding the double length cushion H by the provision of toggle links 15, I5, pivoted at the ends at Il 18, to the headboard and to frame 2| and having the center pivot 19 connected by link with the center pivot 28 of the inner frame raising and lowering toggle links 26, 21.

Figs. 2; 3 and 4 show successive positions and operation of headboard 13.

The hinge center 14 for the headboard is located at the inner end of frame 2| and at a height approximating the thickness of the mattress pad I I, so that in the folded relation shown in Fig. 2 it will lie flat between the folds -of the pad. In the unfolding relation the frame 22 lifts away from the lowered headboard, as shown in Fig. 3,-before the linkage-described becomes effective to raise the headboard. Finally, as the parts become fully unfolded and straightened out in the horizontal relation shown in Fig. 4, the linkage 26, 2-1, 80, Hand 15, will pull the headboard into upright position, the parts locking in this relation by the toggles 26, 21., reaching or passing dead center relation.

The reverse action takes place in folding from the bed to the hassock-forming condition. it being noted particularly in Fig. 3 that the headboard 13 will .be folded down into holding position over the mattress pad before that pad reaches the doubled-up condition, resulting in the finally folded condition shown .in Fig. 2.

The lowering of the three spring frames 2|, 22, 44, into the base-forming frame |8, as shown in Fig. 2. is of special advantage in that it reduces the over-all height in the folded position to a convenient and comfortable seating height for a ha'ssock, and this compacted or condensed relation of the parts avoids any waste space.

The folded structure, therefore, is as small and compact as may be desirable for a. hassock, and this is accomplished without reducing the overall dimensions of the bed, for the three folding sections of the hassock will provide the frame of a full size bed.

It will be clear from the foregoing that in the folded relation shown in Fig. 2 the parts are securely locked by engagement of leverage extensions 53 of intermediate pivoted legs 46 with the catches or keeper lugs 54 on the sides of posts I8, and by engagement of hook 65 on the upper or outer frame section 44 with catch 66 on intermediate frame 22.

In this condition the device provides a substantial, practical hassock-forming foundation with a top cushion l 6 and may be used for general hassock purposes.

Instead of an ornamental slip cover such as shown in Fig. 1, other covers may be employed, such as a cover simulating the appearance of a wall cabinet or stand, and which could be applied with the folded device standing on its side instead of resting on the bottom. The locked condition permits of this turning the device on its side, enabling it to be placed against a wall and used as a table, or to be stored in this position in a closet or the like. Casters or feet may be provided on the base frame for supporting it flat or on edge and to aid in shifting about.

To unlock and extend into bed-forming position, the locking rod 63, Fig. 7, may be grasped by the handles 12 and turned to rock the hook 65 out of engagement with catch 66, and then these same handles be used to pull out the top and intermediate frame sections 44, 22, through the Fig. 3 position to the fully extended relation shown in Fig. 4.

In this unfolding relation the inner frame section 2| will be raised from the Fig. '2 position to that shown in Figs. 3 and 4, by the straightening of the toggle links 26, 21, and the upward swinging of links 36, this operation assisted by the pull of the springs 51 and 59.

In the fully extended relation, Fig. 4, the toggle links 38, 39, straighten out to lock the frames 2!, 22, and connecting hinge linkage 23 in extended relation firmly supporting the mattress pad 11 fully flattened out and in abutting engagement with the single mattress pad I 6 carried by the outer frame.

Also in the extended position the folding intermediate legs 46 are locked by the lugs 55 overstanding the brace links 50, Fig. 4.

The fully extended bed, therefore, is firmly locked and will not collapse under pressure applied at the hinge connections or elsewhere.

The hinged relation between the-three bedforming frame sections enables the device being shortened to form a child's bed or crib.

As shown in Figs. 9 to 12, the outer or top frame section 44 may, if desired, be swung in under the intermediate frame section 22, about the connecting pivot 45, thus shortening the bed structure to the combined length of the hingedly connected sections 2| and 22, amounting to the length of the double or foldable mattress pad H.

A removable side frame may be used in this partially extended condition, the same being shown as made up of side boards 8|, hingedly connected at their ends at 82 with end boards 83 hinged together at 84.

Legs 85 are shown pivoted to the "side boards at 86, in position to swing down over the outer end of frame 22, and which frame has screw iii seats 81 to receive the thumb screws 88 or like fasteners which can be passed through the openings in the legs into the end of the frame to support this end of the frame and to secure the legs in upright position.

At the other end the side boards 8| are shown secured to the headboard 13 by angle plates 89 reaching around the edges of the headboard and through which thumb screws or other fastenings 90 are passed into the headboard.

The folding frame 8!, 83, is quickly attachable and detachable and may be easily applied to convert the partly unfolded structure into a shortened bed or crib such as shown in Fig. 9.

The invention has the advantage of automatically extending the mattress out into flattened condition, ready for use, in the simple act of opening and unfolding the connected frames, so that there are no heavy operations of separately handling the mattress. The mattress pads are attached to the frame sections so as to move therewith. The fastenings for the purpose may be in the nature of tapes or the like, so that the pads may, when desired, be readily removed for cleaning or replacement.

The motions of the mattress carrying frames are substantially counter-balanced so that very little effort is required in the extending and folding operations. The parts fold naturally and easily into position, one over the other, it being noted that levers 33, pivoted on the base, support the inner end of the intermediate frame 22 and also, as the parts are lowered, serve to swing this frame inwardly into alignment over the lower, inner frame member.
